Diseño e implementación de un sistema de oxigenación para cultivo de tilapia alimentado con energía fotovoltaica

Abstract

This book presents the design and implementation process of an oxygenation system powered by photovoltaic energy used in four geomembrane lakes for tilapia cultivation, located in Campoalegre - Hobo Road, kilometer 8, Huila department. In accordance with the requirements, the current actuator (A 1600𝑊 Blower) for the system must be changed out for one with lower energy consumption; as well as maintaining the level of dissolved oxygen at a minimum of 4 𝑚𝑔𝑂2/𝑙 during the period between 6:00 p.m. to 6:00 a.m.. Therefore, a general characterization of the current system was carried out. The new actuator was chosen and the photovoltaic system was designed following conventional guidelines and methodology. This system was simulated using Matlab's software through the Simulink tool and it was found that according to the weather conditions of the region along with radiation and temperature that the established design did not allow the batteries to be fully charged reaching only 66.6% of their overall capacity. This meant that the autonomy time was not enough to keep the actuator operating during the indicated period. Due to this problem the system was redesigned and simulated again, reaching a 99.9% recharge of the batteries. An autonomous photovoltaic system was installed, the energy consumption of the system was reduced when utilizing with the 𝑅𝑒𝑠𝑢𝑛 𝑀𝑃𝑄−906 120𝑊 𝐷𝐶 compressor and 5.24 𝑚𝑔𝑂2/𝑙 was guaranteed on average, which represents 14% more oxygen than the previous system.
